ANDREW J. GOULD, OF QUINCY, CALIFORNIA.

WATER-WH EEL.

SPECIFICATION forming part of Letters Patent No. 518,599, dated April 24,1894. Application filed December 80,1892. Serial No. 456.813. (N0 model.)

To all whom it may concern.-

l 3e it known that 1, ANDREW J. GOULD, a citizen of the United States, residing at Quincy, in the county of Plumas and State of Cali-. fornia, have invented a new and useful Water-Wheel, of which the following is a specification.

This invention relates to water wheels of that class having buckets secured to the periphery of the wheel and receiving the impact of a stream of water under pressure from a nozzle, and the same is designed as an improvement on Letters Patent No. 291,894, granted to me January 15, 1884; and it has for its primary object to provide a wheel that will effectively prevent any loss of power from back pressure and which is so constructed, as set forth by this improvement, that the same will present a bucket of sufficient capacity to receive a full head of water directed therein.

With these and many other objects in view which will present themselves to those skilled in the art, the invention consists in the novel construction of water wheel buckets hereinafter more fully described, illustrated and claimed.

In the accompanying drawings;*Figure 1 is a perspective view of a water wheel constructed in accordance with my invention. Fig. 2 is a detail in perspective of one of the buckets and a portion of the wheel to which the same is connected, part of the bucket being broken away to expose the interior construction. Fig. 3 is a detail front elevation of one of the buckets and the portion of the wheel to which the same is attached. Fig. 4: is a detail plan view of one of the buckets.

Referring to the accompanying drawings; A represents the water wheel adapted to be mounted upon a horizontal shaft and which is of any suitable constructionand material. The flat rim or periphery of said wheel is provided around its entire length with a series of inclined notches or indentations B which are so constructed as to form straight back walls I) and the forwardly extending diverging side walls I).

Located directly over each of the notches or indentations upon the periphery of the wheel are the series of water buckets C which may be either integrally cast with the water wheel proper or are secured thereto as illustrated in the drawings, by a single set of screws passing through the body thereof and entering the periphery of the wheel. Each of said buckets G is provided with a solid portion 0 having a straight wall 0 and forwardly extending diverging side walls a, said straight back wall and the diverging side walls registering with the back and side walls respectively formed in the periphery of the wheel and extending above the same, thus forming a single back and side walls having an increased impact surface against which the stream of water playsand is discharged therefrom, being of sufficient size to receive the full head or stream of water directed therein from a nozzle, as illustrated in my former patent. The said buckets are also provided with the forwardly extended inclosing top plates D from the forward end of which depend the integral division walls E bearing or resting upon the periphery of the wheel beyond the indentations B and converging inwardly toward the straight back walls of the buckets, thus forming the central water receiving openings F and the enlarged lateral escape or discharge openings G, the angle of said division walls corresponding to the angle of the side walls in the bottom of the buckets. It can be readilyseen, from the construction of the rear or-inner walls of the buckets, that an increased impact surface is formed for the stream of water to play against and thereby provides an additional bucket capacity which accommodates a large head of water, while the dispositin of the lateral escape openings provides for a free discharge of water which also at the same time materially assists in turning the wheel and eifectually prevents back pressure. 7

It will be obvious that the construction herein described provides an improved water bucket, a part of which is formed in the solid body of the rim of the wheel, thereby securing several points of advantage over my former patent. In the first place it is to be noted that in the present construction the projectin g part of thebucket does not extend beyond the periphery of the wheel a greater distance than the projection of the old form of bucket shown in my former patent, but in the present construction the bucket, as an entirety,

is made much deeper and can therefore aecommodate a jet from a'nozzleof greaterdh ameterthan the nozzle which must be e111- ployed, to force a jet or stream ofmwater into 5 the 01d bucket.

of the wheel'are not at all increased,--while the jet-receivingcapacity of the buckets of the wheel-is materially increased-.-; Further? to more, sincethe jet is arranged to strikethe entire Width of the backwall of the bucket 1 at right angles, the strong-rim of the Wheel bears its share of the "force; of the jet, and therefore relieves theprojecting part of the 15 bucket of much strain, consequently'provid-j inga much stronger bucketthantheone" claimedin my old patent, and still another point is to be observedin the factthat by reason of the increased depth of the new 20 bucket herein described, the resistance to the a discharging water is greatly'lessenedandthe free and easy discharge .greatly irnproved.

Having thus described my invention, What r I claim, and desire to secure by Letters Pat- 2 5 cut, is-

As an improvement in water Wheels, the
